Monitors multiple cloud environments and integrates well with other tools
Pros and Cons
  • "It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture."
  • "The support and the pricing can be better"

What is our primary use case?

There are lots of use cases such as finding threats, attack factors, and logs. It helps with rogue DNS or brute force attack detection. We have logs related to why a particular account was created. There is alerting. We can get some false positives, but by fine-tuning some of the things, we can reduce false positives.

Splunk is a security monitoring tool. It helps with incident handling, data logging, and observability of metrics. Splunk can handle all these things. Splunk Enterprise security is a premium app of Splunk through which we can have all the threat intelligence and incident reviews. It helps in finding all the attacks and Advanced Persistent Threats (APTs).

We also have dashboards. We can collect logs from different sources and applications. We can also troubleshoot issues. If we are having any issues with an application, we can go to that particular index to see what is the cause. If any application is failing or giving an error, we can troubleshoot the issue. We do not have to log into the server to find the error.

How has it helped my organization?

We monitor multiple cloud environments. We have GCP, Azure, and AWS. It is easy to monitor multiple cloud environments using the Splunk Enterprise Security dashboards. Splunk releases inbuilt apps, so by using those apps and add-ons, we can integrate it with our cloud environments. For example, for Azure, they have a Microsoft Cloud Services add-on. We need to register the app in Azure, and after registering the app, we have to use the tenant ID and set it up. There are a lot of inputs, and we can use all those inputs to onboard different logs from Azure. There is also the capability for HTTP event collection.

We have a hybrid environment, and that works best for us. For a lot of things, we cannot just go fully cloud. Hybrid is the best option for us. We are happy with the visibility that Splunk Enterprise Security provides. It is also about how we configure things. If we do not do it in the right way, we will not get visibility. We have to know what kind of tools we are using and what kind of data we are pulling. We cannot pull everything. We have to know what to pull. If we pull only what is required, we would not have any problems.

Splunk Enterprise Security comes with MITRE ATT&CK and Cyber Kill Chain frameworks by default. There are 12 processes in the MITRE ATT&CK framework. We just have to onboard logs, create the data models, and assign those ATPs to monitor all the kill chains. We can monitor all attack vectors and persistent threats that we want to monitor.

Splunk Enterprise Security is good for analyzing malicious activities and detecting breaches. I would rate it a 9 out of 10 for that. It can also go to 10 for different clients based on different requirements.

Along with Splunk Enterprise Security, we also install another Splunk app that has all the threat intelligence. We then feed the data through a CSV file and create the use cases. We set up alerts for those. In the case of an event, an alert is generated and assigned to a particular SOC analyst. There can be some false positives, but with proper configuration and filtering, they can be reduced.

Splunk Enterprise Security has been very beneficial and valuable for us. Our application teams can use the indexes to troubleshoot the issues they are facing at their location.

What is most valuable?

Being able to ingest data from all the tools and all the apps being used in the environment is valuable. Being able to create alerts when, for example, the CPU usage reaches 95% is also valuable. We can set up alerts and proactively fix the issues. Splunk helps with all these things, and Splunk Enterprise Security has almost 2,000 use cases. It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture. We can onboard all the logs through indexes and create dashboards to view what is going on in the environment.

What needs improvement?

Overall, it is pretty good. They are improving it every day. They recently released SC4S for onboarding syslog data. However, the support and the pricing can be better.

Buyer's Guide

June 2026
Learn what your peers think about Splunk Enterprise Security. Get advice and tips from experienced pros sharing their opinions. Updated: June 2026.
904,680 professionals have used our research since 2012.

For how long have I used the solution?

It has been 8 years since I have been using Splunk. I am not a part of the core security team. I handle some parts of enterprise security, such as SIEM data models or the creation of some correlation searches and use cases. The majority of things, such as threat hunting or threat intelligence, are managed by our core security team.

What do I think about the stability of the solution?

We faced some issues, but we fixed them ourselves. We have around 10,000 knowledge objects running. All the knowledge objects should not be running all the time. They should be distributed over 24 hours so that the servers do not have any extra pressure at a particular time. We used to have an issue with our indexes going down. The CPU was being utilized 100%, and everything was getting stopped. We found the issue. We fixed that, and we are good now.

What do I think about the scalability of the solution?

It is pretty easy to scale. For Splunk Cloud, we log a ticket with Splunk support, and they start the process. It does not take much time. However, there is a cost involved in that. 

We have been ingesting 40 TB a day. We have three locations: The USA, the UK, and France.

How are customer service and support?

The SLA for Splunk Cloud support is not satisfactory for a customer. The turnaround time is a bit low. That should be fixed. I would rate their support a 9 out of 10.

Which solution did I use previously and why did I switch?

I have not used any similar solution in my current organization.

In my previous organizations, I have used solutions such as Elk, IBM QRadar, and Microsoft Sentinel. Microsoft Sentinel is good. Splunk is better than QRadar. Splunk has a lot of capabilities. It makes it easier to do many things and do them correctly. It does not require as much effort as required in IBM QRadar and Microsoft Sentinel.

Splunk is a bit costly, but if we control our usage during our searches, its cost is okay. When not controlled, it becomes a bit costly.

To those evaluating Splunk and solutions, I would advise knowing the features they would be getting. Elk is open source, but there is an underlying cost of infrastructure. The cost almost becomes the same. You have to hire people who can work on Elk and then you have the underlying infrastructure cost.

How was the initial setup?

We were on-premises, but we recently moved to Splunk Cloud. We have been using Victoria for the last eight months. When going from on-premises to Splunk Cloud, Splunk recommends engaging professional services. 

What about the implementation team?

The migration was done by Splunk. For administration and maintenance, we have about eight people, but the number of users in the environment would be in the thousands.

The maintenance of Splunk Cloud is taken care of by Splunk. Customers do not manage the clusters. With the on-prem setup, we have to patch the servers, upgrade the servers, or restart them from time to time so that the rebalancing of the buckets happens properly. In Splunk Cloud, we do not have to do these things. We only take care of the data normalization part. All other things are managed by Splunk.

What was our ROI?

It does provide a return on investment.

What's my experience with pricing, setup cost, and licensing?

It is a bit costly.

What other advice do I have?

Be clear about what you want and try to filter out as much as possible. Create role-based rules and assign them to users rather than assigning every role capability to all the users. Also, everyone should not have access to all indexes. Only certain people should have access. For example, if someone is from the AD team, he or she should have access to the particular index logging the AD logs. They should not have access to all of it. There should also be some kind of training before you give access to people so that they know which searches to use and which ones not to use. They should understand the impact of various things.

I would rate Splunk Enterprise Security a 9 out of 10 based on my experience and the work that I do with the core security team. They are pretty satisfied with it.

Good visibility, helpful integrations, and very good documentation
Pros and Cons
  • "The security part is useful as it helps secure the entire environment."
  • "The user experience could be improved."

What is our primary use case?

My role is to design and implement and manage a strong environment. I need to ensure the available insights can be extracted efficiently and I use the solution for that. I also configure the Splunk custom dashboard and optimize searches to meet specific business needs. We also do a lot of troubleshooting and upgrading.

What is most valuable?

The security part is useful as it helps secure the entire environment. I designed the security aspect of it for a lot of applications in my company. It's the security thread within the application that we build. I'm able to use Splunk to secure the applications. 

We use the solution to monitor multiple cloud environments. We can monitor even on Amazon products. It's a good source for monitoring all types of applications. 

I can manage and correlate different kinds of searches within my environment. It's good for performance monitoring as well. I can do auditing and reporting through Enterprise Security.

The solution gives us visibility into multiple types of environments. There's a good level of cost optimization as well. It's good for end detection and prevention. I can identify anomalies and get a data view of fraudulent activities. You can uncover the source type and the IP address from where things originate.

Splunk gives us the capability to handle insider threat detection. I'm able to create my own dashboard that will visualize the information. It does depend on how you handle the configuration and permissions. 

We do use the MITRE ATT&CK framework. It helps us discover the scope of the incidents. It helps us to target incidents immediately. We're able to quickly resolve it and stop it. We get data visibility to see what's coming in, which helps us act fast. 

We can work with data from any source as long as you configure it correctly.

The solution has helped us to reduce our alert volume. You can tune your alert thresholds. You can also create rules to define your alerts. It gives you the capacity to optimize queries as well. 

What needs improvement?

They didn't use to be able to integrate with Cisco. However, this has changed now. 

Some minor features could be added. However, I need to do more research. 

The user experience could be improved. It could be more intuitive.

There should be a way to do bulk visualization reporting. 

For how long have I used the solution?

I've been using Splunk for 7 years. 

What do I think about the stability of the solution?

We haven't had any downtime. The only issues come up is if there is an extension of limits. If you extend beyond your license, you may get downtime. 

What do I think about the scalability of the solution?

The solution is scalable. It's easy to manage. 

How are customer service and support?

We have contacted technical support for troubleshooting. No solution or machine is perfect. We had an issue where a new hire misconfigured some servers and they were able to offer us support. They are helpful, however, they do need to be faster in response. They do provide a to of documentation that can be helpful. 

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

I'm also familiar with CloudWorks. However, Enterprise Security has more features and can provide more insights. 

I'm familiar with Dynatrace.

How was the initial setup?

Splunk was already in place when I arrived. I simply tried to implement different strategies in multiple environments. 

What's my experience with pricing, setup cost, and licensing?

Splunk is pay-as-you-go. The pricing depends on your use case. You only really pay for the amount of data you are dealing with. 

What other advice do I have?

I'm a Splunk customer. 

People shouldn't necessarily look for the cheapest pricing. You need to look at what will optimize costs and the time it takes to secure the data. The most important thing, before cost, is being able to successfully secure your data. You should choose your solution based on your use case as well. 

I'd rate the solution 8 out of 10. 

Which deployment model are you using for this solution?

Helps with the functioning of an organization's security operation center and to detect anomalies in data
Pros and Cons
  • "The solution's most valuable feature is that it helps with our use cases to detect anomalies in our data and it is important to my company since we have a lot of data on different logs on the systems."
  • "Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team."

What is our primary use case?

The solution is used in my company to help the security operation center in work areas like detection, response, and investigation while maintaining cybersecurity standards.

How has it helped my organization?

My company has benefited from using Splunk Enterprise Security, which has helped us stay out of the headlines in newspapers. The tool helps detect threats early and respond to them effectively.

What is most valuable?

The solution's most valuable feature is that it helps with our use cases to detect anomalies in our data and it is important to my company since we have a lot of data on different logs on the systems. We need to be able to create insights that are indicative of malicious activities, which is one of the main purposes of having Splunk Enterprise Security in our company.

What needs improvement?

The product lacks cross-cutting capabilities. The features in Splunk Enterprise Security that were initially promised to our company are still not available. My company has been asking Splunk for some of these features to be provided in the product for years, and we have been promised that they will be introduced soon in the solution and be part of the product's next release.

I believe that the contract and the terms and conditions mentioned in it are areas where improvements are required.

For how long have I used the solution?

I have experience with Splunk Enterprise Security.

What do I think about the stability of the solution?

When it comes to the on-premises version, the stability of the product was quite reliable. When my company moved to the product's cloud version, we faced some major issues related to availability and dealing with events like data corruption.

What do I think about the scalability of the solution?

The product's scalability is okay. I do not think my company faced issues in the area of scalability.

How are customer service and support?

The product's support services were not great initially, but now they are in really good shape. Whenever my company connects with the product's support team, they listen to our questions and queries, so I feel that we are in a much better place now. I rate the technical support as eight out of ten.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

My company has experience with ArcSight. We switched to Splunk Enterprise Security because we couldn't get good answers to our questions from ArcSight, and it was just not functional.

How was the initial setup?

The solution is deployed using the cloud services offered by Splunk. Recently, my company also deployed the tool on an on-premises model. In our company, we monitor both, cloud and on-premises, with our cloud instance.

In the beginning phase, I would describe the deployment experience as a costly and hard process. The migration process from on-premises to cloud was hard and took our company a year to complete. There were different kinds of roadblocks on our company's and Splunk's end. My company worked directly with the migration process associated with the product.

What was our ROI?

It is difficult to say whether I have seen an ROI since it is like trying to figure out how much an insurance policy works. I think that our company will receive a return on investment from the use of the solution since it helps the organization's cybersecurity team stay out of the newspapers. My company has always been able to deal with threats quickly with the product.

What's my experience with pricing, setup cost, and licensing?

Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk. Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team. I like the direction Splunk stays in by thinking with the customers about how to reduce costs and only have that data searchable or available, which you need at a particular time. I like the path Splunk is going on, specifically its current trajectory. I appreciate the efforts put in by Splunk in the area partnership, which is what my company expects.

Which other solutions did I evaluate?

My company uses Microsoft Sentinel. A multi-SIEM environment provides my company with the best of both worlds. Sentinel has some good features, like Microsoft Graph Security, that the tool uses for the whole Microsoft ecosystem. Microsoft Sentinel is a good option for my organization.

In my company, Splunk acts as a product that complements Sentinel because the former lacks some features. I think Microsoft is strong in the area of service delivery. Microsoft's EDR tools, like Microsoft Defender, use Servers from Microsoft Graph Security, and my company benefits from such a type of integration, and we are able to send alerts to Splunk. In our company, if we start to ingest all the data we usually ingest in Splunk by moving to Sentinel, it will become too expensive, so we have to choose where to keep our data.

What other advice do I have?

My company has been able to reduce the mean time to resolve with Splunk Enterprise Security as it went down from a couple of days to hours.

My company has seen a significant reduction in alert volume. It was very noisy earlier, but lately, my company hardly sees any false positives.

It is super important that the solution provides end-to-end visibility of our company's environment because you can never know from where threats can materialize. The fact that users can correlate and ingest data makes sense and is crucial, considering the massive amounts of data.

Splunk Enterprise Security has helped improve our company's ability to ingest and normalize data, which is one of the tool's key benefits.

I would not say that Splunk Enterprise Security has helped solve problems in real-time scenarios, but it has helped solve problems on a near real-time basis. In my company, there is always some lag between the data that comes in and the ones being ingested and correlated. Splunk Enterprise Security aids in solving problems in a matter of minutes.

Splunk Enterprise Security provides relevant context to help guide our company's investigations, and it is very important and can be considered everything for our organization. In our company, we pull in data from assets and registries to give index-based alerts and be able to find owners quickly to notify them and respond to threats.

Splunk Enterprise Security's ability to help our company find any security events across environments is excellent. My company is really happy with Splunk Enterprise Security. The product helps our company find bad stuff when needed.

The truth is that it is very hard to deliver solutions that work at a certain scale. I think that one of the things I could say is that it is a solution that scales up at work. There are many organizations where solutions fail, and I can say that since I have been a part of the deployment of many other tools, it is hard to get many products to work. Splunk Enterprise Security works, and our company's analysts rely on it and trust it. I can only see improvements considering the strategies in terms of where the product's management team is going, and I believe that I will be able to rate the tool a nine out of ten pretty soon.

I rate the overall solution an eight out of ten.

Helps improve our incident response time, and provides great visibility, but the deployment is complex
Pros and Cons
  • "Splunk Enterprise Security's dashboards are a key asset."
  • "The presence of multiple layers creates a significant challenge for monitoring across cloud environments."

What is our primary use case?

We use Splunk Enterprise Security for threat detection on our network devices.

How has it helped my organization?

Splunk Enterprise Security excels at threat detection. We've developed multiple correlation searches leveraging security data. These searches identify threats and categorize them by urgency level, enabling our security analysts to prioritize and take swift action.

Splunk Enterprise Security has helped us improve our incident response time. We achieve this by ensuring our queries are completed in near real-time.

Access management focuses on storing and managing access controls, while identity management deals with user identities. For example, if we want to find IP addresses associated with CrowdStrike, we can use access management to look up their IP ranges. Then, we can check if any IPs match by adding them to a specific identity management lookup. Finally, by leveraging the combined identity and access management features of Splunk Enterprise Security, we can create correlations between these entities.

The security dashboard can be customized to display the information we need most quickly. It typically has seven to eight panels, each dedicated to reflecting specific data. While some initial data load time might be present, clicking on a specific panel will display its information as soon as possible. There can be delays in traditional dashboards when searching for specific data. To optimize this, we can create "base searches" within each panel. These predefined searches cover commonly used queries and fields. Alternatively, we can create a "summary index" that holds a longer span of pre-processed data. This summary index allows even large datasets to be displayed quickly when accessed through the dashboard.

Splunk enhances our team collaboration regarding security incidents. When a threat alert is received, we can click on it and choose "investigation in progress" from a dropdown menu. This selection redirects us to a dedicated investigation page for further details. For in-depth analysis, we can drill down into the logs to pinpoint the source of the issue. Additionally, the platform allows us to contact network devices to determine the root cause. Once the issue is resolved, we can close the investigation.

We monitor both AWS and GCP environments using Splunk Enterprise Security. 

Splunk provides threat intelligence capabilities that can be valuable. This, combined with the comprehensive set of dashboards available, allows us to effectively monitor for threats. We can also create custom apps within Splunk for threat detection. These apps can include custom dashboards or reports that display specific information. For example, we could create a dashboard that shows the number of users accessing unknown URLs or another that monitors a particular device for suspicious activity. An example of suspicious activity might be a device where the print command is being executed repeatedly but failing each time. This could indicate a malfunction or, potentially, a malicious attempt to exploit the system. Similarly, a sudden spike in activity, such as millions of clicks on a specific device within a short timeframe, could also be a sign of a threat. By monitoring these parameters within Splunk's threat detection features, we can identify and investigate potential security incidents.

Splunk provides valuable visibility across multiple environments. Whether we have an on-premises or cloud architecture, Splunk offers self-monitoring capabilities. Additionally, depending on our environment, we can leverage existing monitoring tools. For on-premises deployments, we can utilize the Martin Console alongside Splunk for comprehensive monitoring. Cloud environments often come with built-in monitoring handled by the cloud provider's support team. In such cases, Splunk can focus on applications and custom log data for deeper insights.

The threat topology provided by Splunk gives us a comprehensive overview of potential threats. By analyzing queries or notable events, we can identify and neutralize these threats.

Splunk does a good job of analyzing malicious activities.

Splunk has improved our organization's decision-making by centralizing all the information in our environment and allowing us to access multiple dashboards and reports in one place.

Splunk has helped us reduce our alert volume. By using Splunk, we can identify the root causes of failures, which in turn leads to a decrease in alerts.

Splunk accelerates our security investigations by enabling us to resolve issues and document them in Standard Operating Procedures or knowledge-base articles. This facilitates a swifter response to similar incidents in the future.

What is most valuable?

Splunk Enterprise Security's dashboards are a key asset. They offer comprehensive visibility across our entire environment, allowing us to diagnose and address security issues directly from the interface.

What needs improvement?

I would like Splunk to offer a quicker and easier way to run queries.

Splunk could improve its cost-efficiency for our organization by offering pre-built architectures tailored to specific environments. This would provide a clearer picture of required licenses and their implementation, ultimately reducing licensing costs.

The presence of multiple layers creates a significant challenge for monitoring across cloud environments.

For how long have I used the solution?

I am currently using Splunk Enterprise Security.

What do I think about the stability of the solution?

Splunk Enterprise Security is a very stable product, but there are occasional bugs that can appear.

What do I think about the scalability of the solution?

We can scale Splunk Enterprise Security up or down depending on our demands.

How are customer service and support?

The Splunk support team is helpful. For complex issues or on-demand requests, we raise cases with them. On-demand requests requiring impactful solutions are paid. However, for UK-based users, standard support is free and usually resolves issues efficiently. In some cases, the support team rushes to provide a solution without even looking at the issue.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial deployment can be complex. It involves creating multi-site clusters for each location and configuring a cluster master for each. This is because the cluster master will replicate data across multiple sites, making the environment more complex.

Four people were required for the deployment.

What other advice do I have?

I would rate Splunk Enterprise Security 6 out of 10 because of the complexities that occur at times.

I highly recommend Splunk Enterprise Security for organizations seeking comprehensive security monitoring. Splunk offers a centralized platform to collect and analyze vast amounts of security data. This empowers us to gain full visibility across our entire IT environment, including applications, user activity, and potential security threats. Splunk provides insightful dashboards, reports, and real-time alerts to help proactively identify and address security issues.

While cost is a consideration, prioritizing features over functionalities for SIEM solutions can be risky. It's best to identify your business needs first and then choose an SIEM that offers the most relevant benefits to address those needs.

Splunk Enterprise Security is deployed across multiple locations and departments within our organization.

Splunk Enterprise Security required maintenance.

User-friendly, feature-rich, and best support
Pros and Cons
  • "It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective."
  • "The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost."

What is our primary use case?

There are many use cases. Most of the use cases are related to security, data integration, and data sources. 

How has it helped my organization?

Splunk Enterprise Security helps with real-time detection. When we integrate any data source, if any external IPs or external devices are accessing that data source, we get notified. We get alerts based on the use cases we develop.

Splunk Enterprise Security has improved the incident response time a lot. Splunk is doing log ingestion, and it is also used to search the database for issues. It is ingesting and identifying. All that is happening in a single solution.

Splunk Enterprise Security is very easy to use. We can monitor anything. We can monitor and integrate any type of applications and servers. It is very easy and effective. I work with different security tools, but none of the security tools has these many features.

Splunk's documentation is clear. Irrespective of the environment we are working in, we have clear documentation.

One of our clients is using the Threat Intelligence Management feature. The actionable intelligence provided by the Threat Intelligence Management feature is very good.

I have been working with different vendors. Splunk Enterprise Security is a very effective and user-friendly tool. Whether it is Sentinel, LogRhythm, or QRadar, each one of them has its own limitations, but Splunk has all the features.

Its benefits can be realized very quickly. It does not take lots of days or months.

Splunk Enterprise Security has helped to reduce our alert volume. There is a 60% to 70% reduction.

Splunk Enterprise Security has helped speed up our security investigations.

What is most valuable?

It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective.

It has multiple features. It has data integration, search, reporting, and alerting.

It does not need any advanced programming. It only requires basic programming.

What needs improvement?

In terms of features, it does not need any improvement. Everything is good so far. The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost.

For how long have I used the solution?

I have been working with Splunk for more than 7 years. I have worked with Splunk Enterprise, Splunk Enterprise Security, Splunk Cloud, and on-prem Splunk.

What do I think about the stability of the solution?

It is very stable. We never had any issues or bugs.

What do I think about the scalability of the solution?

Its scalability is good.

How are customer service and support?

The support from the Splunk side is very good. They provide the best support.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have used Sentinel and QRadar. I switched because of the advanced features, support, and good documentation. It is very effective. It is the best solution. The only problem is the cost.

How was the initial setup?

I have worked with cloud deployments and on-prem deployments. Its initial setup depends on the environment. It is sometimes complex, and sometimes, it is very easy. We also get good support from them.

Our implementation strategy has 3 phases. We first go for development, and then we go for Pre-Prod. After that, we move to Prod.

What about the implementation team?

Currently, I am the only one handling the deployment, but when it comes to operations, we need at least two to three people.

It requires maintenance. Generally, 2 people are required, but for my clients, I am the only one who is taking care of the maintenance.

What was our ROI?

We have seen an ROI.

What's my experience with pricing, setup cost, and licensing?

It is expensive. I work for multiple clients. I am working for more than 5 clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel.

What other advice do I have?

I would recommend Splunk Enterprise Security to anyone who is looking for a similar solution. This is the only solution with all these features.

I would rate Splunk Enterprise Security a 9 out of 10. It is stable, user-friendly, and feature-rich. It is very helpful. Even though it is expensive, the stability, support, and technical documentation make it very effective.

The solution speeds up our response by enabling us to automate some of the investigation steps
Pros and Cons
  • "Splunk's interface is user-friendly, and it has apps and add-ons for most applications. We can easily normalize the data to make it readable and understand the logs. We easily get all the field extractions and enrichment done by using the apps and add-ons. This helps us understand the application logs because the raw data is useless unless we extract some useful information from it. These add-ons make it so much easier."
  • "It would be nice if Splunk reduced the cost of training. Their training sessions are way too costly."

What is our primary use case?

I work in security and use Splunk for endpoint and application security, use case development reports, etc. I haven't used Splunk much for threat intelligence. We have a threat intel feed configured, and we create use cases based on those and the recommendations by the threat intel team. If something isn't covered, we create a use case for it. For example, if an application has an authentication interface enabled, we check all their authentication mechanisms and all the login policies. 

How has it helped my organization?

Splunk speeds up our incident response by enabling us to automate some of the investigation steps, such as finding information about the user or the source of the incident on machines. We can then move directly into the remediation phase and assign those tickets to the remediation team. It also triggers automatic email alerts to the recipient user. If our security analyst wants to see the alert logs or anything, they can easily drill down to identify any information required.

It allows us to configure use cases involving our machine-learning toolkit, and we have an adaptive threshold in ITSI. Using these tools, we can eliminate false positives and do some whitelisting to weed out users who are performing benign activities. Removing the false positives reduces the incident response time.

We can start to see results immediately once we have achieved a steady state. For instance, we can easily show how much our mean resolution time for incidents has fallen and provide metrics in a way that is easy for our clients to understand. 

What is most valuable?

Splunk's interface is user-friendly, and it has apps and add-ons for most applications. We can easily normalize the data to make it readable and understand the logs. We easily get all the field extractions and enrichment done by using the apps and add-ons. This helps us understand the application logs because the raw data is useless unless we extract some useful information from it. These add-ons make it so much easier.

Dashboards are useful when we present things to management. They want the numbers and the results. The leaders aren't interested in what we are working on. We need some visualization for our presentations. Splunk has beautiful and useful visualization and dashboard alerts. We can easily create visualizations using the available options and create different types of charts, reports, and graphs that are easy for management to understand. We can also provide our leaders direct access to the dashboards, so they don't need to reach out to our team to get this data or we can automatically send them the reports via email. 

Splunk has several useful features, like asset and identity management. If we integrate our asset and identity management properly in this log, it's effortless to identify the user, device, or asset. We can get all the details if we integrate those things into the lookup engine.

What needs improvement?

It would be nice if Splunk reduced the cost of training. Their training sessions are way too costly.

For how long have I used the solution?

We have used Splunk for around seven years.

What do I think about the stability of the solution?

Splunk is highly stable if you meet all the prerequisites and have enough physical memory for your local storage. 

What do I think about the scalability of the solution?

If you use the cloud version you can scale as much as your licensing allows. It's easy to scale, upgrade, or add instances according to your needs. 

How are customer service and support?

I rate Splunk support 8 out of 10. They're good, but I think there is room to improve because Splunk is the market leader, and they should strive to provide the best possible support. 

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I previously used QRadar and ArcSight. Splunk is one of the top products. Compared to Sentinel or QRadar, Splunk is the market leader in features and security. You can integrate application, physical, or cloud security and onboard those logs into Splunk, then tailor it to your requirements. 

How was the initial setup?

I've worked on multiple deployment models for Splunk, including hybrid, cloud, and on-prem. The deployment is straightforward. We do a POC and then scale it based on our requirements. 

What was our ROI?

I feel like Splunk is worth our investment. 

What's my experience with pricing, setup cost, and licensing?

The cloud version of Splunk is somewhat expensive, but it does provide some flexibility because you do not need engineers to manage the system. Everything is hosted in the cloud because it is a SaaS service. It depends on the usage. It is costly, but everything good thing comes at a price.

What other advice do I have?

I rate Splunk Enterprise Security 9 out of 10.

We can create dashboards, speed up our security investigations, and reduce alerts
Pros and Cons
  • "Splunk has a wide range of features that customers use to find and analyze all kinds of logs."
  • "The price has room for improvement."

What is our primary use case?

We provide comprehensive infrastructure support and ingest mine data in three ways. The first is Agent-based where the information is sent from client machines to an agent. The second is TCP port forwarding where data is sent to Splunk through an open port. The third is the HEC token. We then use the Splunk DB Connect app to ingest data as per the client's requirements.

How has it helped my organization?

We are currently onboarding data from AWS to GCP. We are moving data from on-cloud to our production and deployment level environment. Additionally, the data is being added to the services on those machines. To forward the logs to Splunk, we have created a default index, which is a way of storing data in a particular way. We have created the index based on the requirements of the data storage.

Currently, we are ingesting all kinds of government security PI data. Similarly, we can ingest any kind of confidential data into Splunk using masking. This allows us to filter the data and mask sensitive information. For example, if a user account number has ten digits, we can mask out the first six digits so that only the last four digits are visible. We ingest this kind of confidential data into Splunk, and we also ingest PI data and Splunk governance data.

We are using the threat intelligence management feature. We have a separate security team, called a soft team, which is responsible for finding vulnerabilities, threats, and malware alerts in our Splunk environment. We use the threat intelligence management feature to identify any suspicious activity that may be coming from outside users. The soft team continuously monitors these alerts and creates proxy alerts to identify any potential threats.

Splunk's insider threat detection capabilities help us to easily identify threats by using Splunk queries. We have predefined Splunk Insight and are also using the one in the app, which is configured on top of Splunk machines. This allows us to quickly identify how many unknown IPs are syncing into other machines, and we can use this information to identify threats.

We use threat pathology and MITRE ATT&CK. I am currently supporting a financial institution with its infrastructure, which is split into two teams: one for complete infrastructure support, including hosting and operations, and the other for security-related matters. My team is continuously investigating new security threats, so we will take care of the onboarding process. As part of the infrastructure support team, I am responsible for handling all onboarding tasks. If I encounter any security concerns, I will escalate them to the SOC team.

We have a lot of operations using the Mission Control feature in Splunk.

Splunk helps us analyze malicious activities and detect breaches. We are using a Splunk SaaS application in a multi-class environment. To maintain high availability with zero downtime, we have maintained close to 70 indexes and 50 searches. Splunk provides us with alerts from the entire infrastructure, which helps us maintain our service. We use Splunk Mission Control to iron out any issues. For any special needs, we can go to Mission Control to verify and mitigate alerts.

Splunk Enterprise Security has helped us reduce our alert volume. Splunk currently ingests five terabytes of data, and we can set parameters to exclude rotational works and backlogs to reduce the number of alerts.

Splunk Enterprise Security has helped speed up our security investigations.

What is most valuable?

Splunk has a wide range of features that customers use to find and analyze all kinds of logs. For example, they can use SQL queries to identify vulnerabilities. Additionally, they can create dashboards to visualize and filter their data, and to create real-time alerts when thresholds are exceeded. Splunk Vision is a popular tool for data modeling and visualization and is used worldwide.

What needs improvement?

The price has room for improvement.

For how long have I used the solution?

I have been using Splunk Enterprise Security for five years.

What do I think about the stability of the solution?

We are maintaining a multi-cloud environment across multiple regions, and for the last two years, Splunk Enterprise Security has maintained a 99.999 percent uptime.

How are customer service and support?

We open cases on behalf of our customers with Splunk. If the technical support resolution is not up to par, we request a meeting call to work with the support team and resolve the issue for our client.

Which solution did I use previously and why did I switch?

We also use the Red Hat OpenShift enterprise Kubernetes container platform. OpenShift is a more popular container tool with excellent support, but all of our OpenShift deployments are on-premises, along with production clusters around the world.

How was the initial setup?

For the deployments, we scan the data to ensure that the Splunk machines can support it. If we identify anything on the machine, we ask the customer to remediate the issue by upgrading the version of Splunk. Most of our customers are using version 8.3.3.

What other advice do I have?

I would rate Splunk Enterprise Security nine out of ten.

Organizations that value their security should not choose the cheapest SIEM solution. They should expect to invest in a SIEM solution that can meet their specific needs, even if it means spending more money.

Monthly patching maintenance is required. 

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Reasonably priced, helps with compliance, and saves a lot of time
Pros and Cons
  • "The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me."
  • "It will be helpful for customers if they can create some real-world cases, and we can find a case study to align with. I know that Splunk has tremendous potential. We only include a tiny piece of it. There is a lot of stuff that we need to learn. If Splunk can provide more real-time examples, that will be helpful for customers."

What is our primary use case?

We gather all the security logs from all the endpoints, network appliances, and the security filter. We have set up automatic alerts that are sent to system administrators, so we have pretty much real-time alerts about anything that happens. 

How has it helped my organization?

Splunk Enterprise Security has definitely improved my organization. First of all, it helps with compliance. Our organization has something called scorecard requirements. It is an annual self-check checklist. Having alerts set up is one of the requirements, and secondly, we have a local administrator who gets the alerts. That makes our job a lot easier. So, we pretty much know what is going on in a real-time setting.

We are the judicial branch of the government, so we are pretty much into our private cloud. We do have a setup to monitor our private cloud but not outside our organization. If we can monitor one cloud, multiple clouds will not be hard at all. It is easy.

Splunk has absolutely reduced our mean time to resolve. Knowing on time and having firsthand information is very helpful for any organization. We are able to capture what is going on, and the visibility of it is absolutely tremendous. I cannot provide the metrics, but it has saved a lot of time.

Splunk has absolutely improved our organization’s business resilience. We have been using Splunk for the last six or seven years, and I cannot imagine a life without Splunk. 

In terms of Splunk’s ability to predict, identify, and solve problems in real-time, this is something that we will look into. We have not yet looked into machine learning, AI, and all of Splunk. Currently, we are more in the reaction mode, but we are trying to get more in the protection mode or have more proactive measures. We have not got to that point yet, but we will definitely be there.

What is most valuable?

I am not into the administrator type of setup. I am more like an advanced user. The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me.

What needs improvement?

Splunk conferences are very helpful for networking and talking to folks who have a similar situation. It would be helpful for customers if they could create some real-world cases, and we can find a case study to align with. I know that Splunk has tremendous potential. We only include a tiny piece of it. There is a lot of stuff that we need to learn. If Splunk can provide more real-time examples, that will be helpful for customers.

For how long have I used the solution?

It has been six or seven years. 

What do I think about the scalability of the solution?

Splunk has a reputation for being scalable. You can start small, and if your demand increases, you can scale your platform. Splunk does a good job. It allows customers to have scalability so that they can expand their capacity. I would rate it a ten out of ten in terms of scalability.

How are customer service and support?

In our company, we have a Splunk consultant who is very good at providing a solution. So far, I have not had any problem that is unresolved. I would rate their support a ten out of ten. In this industry, there is good support, and there is bad support. Splunk's support is more like Cisco's support. It is pretty good.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We used something else, but I do not remember the name. Splunk is what we have been using for a long time. It is more advanced in terms of IT security. There is more scalability and the capability to do a lot of different things on multiple platforms. This is where it is more advanced than other products.

How was the initial setup?

I was not in the deployment team, but I was involved in the early stage of evaluating all different kinds of products.

What was our ROI?

There are a lot of things for which you can measure a return on investment, but security is something on which it is hard to put a dollar value and measure how much return you have got. However, in terms of helping the administrator or helping the company to put security in place, Splunk does a great job. I cannot imagine a life without Splunk.

What's my experience with pricing, setup cost, and licensing?

The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable.

Which other solutions did I evaluate?

We evaluated what was on the market, and fortunately, we picked Splunk. Looking back, it was the right decision.

What other advice do I have?

Splunk is moving in the right direction and providing better and more mature products. This is my fifth conference, and I see the progress. I see Splunk bringing in all new products. They are pretty much in line with the security trends. They have improved a whole lot to meet customers' needs.

I would rate Splunk Enterprise Security a ten out of ten.

Provides centralized monitoring, customized dashboards, and speeds up security investigations
Pros and Cons
  • "The most valuable features in Splunk Enterprise Security are the cluster capabilities."
  • "The licensing price is high and has room for improvement."

What is our primary use case?

I'm part of the Splunk operations team, which means I support Splunk functionality and occasionally conduct threat management onboarding. We assist various teams with threat-related tasks. If they need help bringing log sources into Splunk, we guide them through the process. Once the logs are onboarded, we create correlations to identify threats, troubleshoot issues, and help mitigate potential risks.

How has it helped my organization?

We handle incidents through a queue configured in our event management system. This includes automated incidents for our Splunk infrastructure, like server health checks, and user-reported issues where functionalities like the fetch score aren't working. We address all incidents, whether automated or user-raised, through this system.

We've made significant improvements to our Splunk infrastructure to support our internal teams. This ongoing effort focuses on helping application teams onboard logs from various applications for their review and troubleshooting. We've streamlined the onboarding process, improved data quality, and ensured smooth data consumption for our internal users.

Splunk Enterprise Security offers multi-cloud environment monitoring capabilities that we can utilize for our users if they require it.

We can build a dashboard in Splunk to centralize the monitoring of critical information. This dashboard can display key metrics for onboarding methods and LogSources we actively track, providing a clear view of our entire monitoring environment.

While Splunk Enterprise Security offers good threat detection capabilities, our current process limits visibility into user activity. When users request correlations, we create the code and configure everything on our end, and then they test and work on it from theirs. This lack of transparency extends to threat management, as we can't directly see tickets in their separate ServiceNow system. If they encounter issues, they share details in a document for us to review and address.

It comes with a large collection of correlation searches, but we'll need to review them to find the ones that match our specific needs for monitoring malicious activity. Once we've identified the relevant searches, we can customize or recreate them within the correlation settings to best suit our environment.

Splunk Enterprise Security helps us detect threats faster.

Splunk Enterprise Security is a good monitoring tool that allows us to track specific details by creating custom queries. For instance, to monitor a particular organization's infrastructure, we would first onboard their logs and then create queries to capture relevant information. This way, any suspicious activity, attacks, or other events would be easily identified within the infrastructure. Additionally, Splunk's checkup operation minimizes the chance of missed alerts by automatically identifying detections, ensuring near-complete coverage of around 99 percent unless there are outages or limitations with global agents.

Splunk Enterprise Security helps us speed up our security investigations.

The customizable dashboard for our security operations is a good feature.

What is most valuable?

The most valuable features in Splunk Enterprise Security are the cluster capabilities.

What needs improvement?

The licensing price is high and has room for improvement.

For how long have I used the solution?

I have been using Splunk Enterprise Security for four years.

What do I think about the stability of the solution?

Splunk Enterprise Security is stable.

What do I think about the scalability of the solution?

Splunk Enterprise Security can scale according to our needs.

How are customer service and support?

The technical support has been successful in resolving the majority of our cases.

How would you rate customer service and support?

Positive

How was the initial setup?

While the deployment process itself is simple, the number of personnel needed varies depending on the infrastructure size and user base. A small deployment for 50 users can be completed by two people, while larger deployments supporting over 500 users may require up to 15 people.

What's my experience with pricing, setup cost, and licensing?

The Splunk Enterprise Security license is expensive.

What other advice do I have?

I would rate Splunk Enterprise Security eight out of ten. Splunk improves user efficiency by streamlining workflows and enabling the detection of anomalies within data.

Splunk Enterprise Security is deployed across multiple locations in our organization.

To ensure our data remains secure, Splunk servers require monthly maintenance. This maintenance includes installing security patches that address vulnerabilities and prevent unauthorized access to our information.

Which deployment model are you using for this solution?

The user interface gives you a single dashboard to directly view all high-level information
Pros and Cons
  • "I like Splunk's automated threat detection and orchestration capabilities. Splunk offers a single solution for analyzing, aggregating, correlating, monitoring, reporting, visualizing, etc. You can get all of these capabilities in one place. On top of that, it provides a cloud, testing, on-premise, and hybrid solution, giving customers more flexibility for their use cases."
  • "We've sometimes faced issues with upgrades. The incident review dashboard sometimes breaks after updates. When we add a space or something in the description or anywhere in the SQL, the drill-down value may be reset with a blank value. Before rolling out any software, they should test it thoroughly and ensure clients won't have issues with the upgraded version. It should be compatible with all or most of the apps. All major issues must be addressed before rolling out the upgrade."

What is our primary use case?

I use Splunk for visualization, reporting, monitoring, log aggregation, and other security purposes. We gather various logs into one place and analyze them based on specific business use cases to get high-level insights that inform decision-making at every level of the organization. We also use it to aggregate other IT logs — not just security. 

Our organization is working in a massive on-prem environment. We're one of Splunk's oldest clients. It's convenient to migrate everything to the cloud, and we would have more flexibility. However, we currently have our resources and everything established to use Splunk on-premises, so we aren't switching to a cloud environment.

How has it helped my organization?

Splunk allows us to monitor logs and track suspicious activity in real time. With the help of the SOAR platform powered by AI and ML, we can respond quickly. Our security posture is better, and we can resolve security incidents quicker. Splunk has improved our visibility by providing critical security metrics in our dashboard and strengthened our security controls. 

The number of alerts we receive is similar to what we saw using our previous solution. While it hasn't necessarily reduced our alerts, Splunk is improving our resolution time and overall security.

What is most valuable?

I like Splunk's automated threat detection and orchestration capabilities. Splunk offers a single solution for analyzing, aggregating, correlating, monitoring, reporting, visualizing, etc. You can get all of these capabilities in one place. On top of that, it provides a cloud, testing, on-premise, and hybrid solution, giving customers more flexibility for their use cases. 

Splunk's real-time monitoring is one of its best features.  The user interface gives you a single dashboard to directly view all the high-level information. The security incident monitoring and investigation page is also very helpful. You can document an investigation step by step. Many investigators can work on a single incident also based on their shifts. Everyone can add notes on the investigation page. 

The incident response features are based on real-time data. The monitoring team can immediately take over an incident and prioritize tasks based on risk scores. We can assign multiple technicians to one security incident based on their skill, improving resolution time.  The incident review dashboard provides many useful details, like the indicators of compromise and risk scores.

We can get threat intelligence from multiple platforms, including the latest known IOCs, to support our response to security incidents. We store the threat data from various sources in a centralized place, and it updates every six to 12 hours. 

The MITRE ATT&CK framework feature is helpful for understanding which phase an incident is in and what the next steps are so a technician can prevent it from progressing. It gives us a detailed overview of other tactics it might be associated with, enabling us to stay vigilant. We can correlate with other simultaneous or sequential incidents and take action to strengthen our security based on these incidents.

What needs improvement?

We've sometimes faced issues with upgrades. The incident review dashboard sometimes breaks after updates. When we add a space or something in the description or anywhere in the SQL, the drill-down value may be reset with a blank value. Before rolling out any software, they should test it thoroughly and ensure clients won't have issues with the upgraded version. It should be compatible with all or most of the apps. All major issues must be addressed before rolling out the upgrade.

For how long have I used the solution?

I have used Splunk for eight or nine years. 

What do I think about the stability of the solution?

I rate Splunk nine out of 10 for stability. 

What do I think about the scalability of the solution?

I rate Splunk eight out of 10 for scalability. Scalability is always a challenge. The larger your environment, the more issues you'll have. There aren't many problems with Splunk on the cloud, but scaling can be challenging in an on-prem environment. If you're ingesting a significant volume of data, you need a proper maintenance routine to maintain your base architecture. Sometimes, it's a bucket application. It can take a few hours to reset those things, and network issues might contribute to that. 

How are customer service and support?

I rate Splunk support eight out of 10. It varies based on your data volume and number of licenses. 

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have used several solutions for different clients, including QRadar, Palantir, and Microsoft Sentinel. Splunk has more capabilities than QRadar. It's also more flexible and user-friendly. You can modify and customize the solution to show you the information you want.

How was the initial setup?

The deployment depends on the environment. It may take only a couple of weeks to deploy Splunk in a small environment, but a larger environment involves a detailed process that may take months. It helps to have a larger staff. It also depends on how process-oriented an organization is. Some organizations will take much more time in the planning and design phase. 

After deployment, Splunk requires a good deal of maintenance, depending on the volume of data you're ingesting and your user base. It may require multiple resources to manage this environment. 

What was our ROI?

Splunk improves our security controls, resolution time, and threat-handling capabilities. We're saving time and resources, meaning more money for our clients. 

What's my experience with pricing, setup cost, and licensing?

I don't know about Splunk's pricing because I work on the technical side, but I know it is a costly platform. There are cheaper products and some open-source ones, but Splunk costs a lot because of the features it provides. Still, the pricing is a concern for many of my clients, and more would use Splunk if they lowered the cost a bit. 

What other advice do I have?

I rate Splunk Enterprise Security nine out of 10. I would recommend Splunk because it covers multiple services in one place. It also has a strong developer community. You can easily get help from community support. Splunk is a versatile product that competes well with leading security tools like Microsoft Sentinel.
